Note: Cross bearing circlip can be steel (conventional design) and plastic (one-time ring that is cut off during disassembly). The disassembly/assembly process is the same in both cases.
Disassembly
Warning: never clamp the driveshaft in a vice to the shaft tube. Distortion of the pipe can lead to imbalance of the shaft. Attach the shaft only to the yoke flange. Avoid scratches or burrs on the sealing surface.
1. Place the cardan shaft parallel to the press table.
2. Mark the front and rear ends of the driveshaft tube.
3. Remove the circlips from the cross bearing caps.
4. If it is not possible to bring the ends of the steel retaining ring together, upset the bearing cover with a light blow on the cover.
5. Install the universal joint so that the bottom of the yoke rests on the socket wrench (tool head) size 30 mm.
6. Install a special fork on the open diameters of the bearings of the cross, squeeze out the lower bearing of the cross.
7. If the bearing has not completely come out, install a spacer between the bearing seal and the bearing ring, press the bearing out as described above.
8. Turn over the cardan shaft. Press out the opposite cross bearing.
9. Mark the relative position of the sliding yoke and propeller shaft tube.
10. Remove the pivot cross.
11. Remove the remaining parts from the hinge fork.
12. Disassembly of the front hinge is carried out in the manner described above.
13. Clear grooves under lock rings and estimate their condition. Replace the yoke if necessary.
14. Clean the cross-bearing seats in the yoke, evaluate the condition of the fit, replace the yoke if necessary.
Assembly
1. Remove the remaining bearings from the pivot cross.
2. Install the bearing in the side seat of the fork. Flip the plug.
3. Insert the pivot cross into the yoke.
4. Press the bearing in until its end cap is flush with the yoke.
5. Install the bearing on the opposite side of the fork.
6. Verify that the trunnions of the spider are correctly oriented on the bearings.
7. Press in the second bearing, if there is misalignment, stop the assembly operation and start over.
8. Push the bearings until the grooves for the circlips open.
9. Install retaining rings.
10. Check up reliability of a latching of a ring. bearing can "spring" to lubricate and prevent the ring from seating, tap the bearing with a sharp blow from a hammer.
